Dried fruit for Aunt Sal, possibly (7)
I believe the answer is:
sultana
'dried fruit' is the definition.
(sultana is a kind of dried fruit)
'aunt sal possibly' is the wordplay.
'possibly' is an anagram indicator.
'aunt'+'sal'='auntsal'
'auntsal' anagrammed gives 'SULTANA'.
'for' is the link.
(Other definitions for sultana that I've seen before include "Pale seedless raisin" , "Sovereign's mother perhaps" , "bit of a fruit cake" , "Dry seedless grape" , "fruity little thing" .)
